How to add Brevo to your website
Brevo is an email, SMS and automation platform formerly called Sendinblue, used by small businesses wanting email and SMS in one place at low cost. Here's how to put it on your own website, which embed option to pick, and what goes wrong.
Quick answer
Get the code from your Brevo account under Contacts then Forms, where subscription forms are built and embedded. For most people the right choice is the embedded form — a subscription form for your page. Paste it into a code or embed block on your site — not a plain text field — then place it beside your main call to action and test the whole flow on a phone before relying on it.
Brevo: which option to use

| Popup form | Triggered signup prompts. |
| Transactional email | Brevo also handles receipts and notifications, which is useful alongside marketing email. |
Step-by-step
- 1
Find the code or link in your account
Brevo keeps this in your Brevo account under Contacts then Forms, where subscription forms are built and embedded. Copy what you need before touching your website — most of the time people lose is spent hunting for the snippet, not installing it.

Pick the right option for the job
The table above is the decision. Embedded form: A subscription form for your page. Popup form: Triggered signup prompts. Choosing before you paste saves rebuilding the section later.

Paste it into a code or embed block
This needs an HTML, code or embed block — not a plain text field, where the code will simply appear as text on your page. On Adviita, ask the AI editor to add an embed section and drop the code in. On WordPress use a Custom HTML block, on Squarespace a Code block (Business plan or above), and on Wix an Embed HTML element.

Put it where the decision happens
An email list is the only audience you own outright — no algorithm sits between you and it. A widget three scrolls down does a fraction of the work of the same widget beside your main call to action. Decide what the page is for, then place it at the point the visitor is deciding.

Check it on an actual phone
Most visitors to a small business website arrive on a phone, and embeds are where mobile layouts break. Open your live site on your own phone and confirm it loads, fits the screen without sideways scrolling, and does not push your contact button out of view. Third-party embeds are also the most common cause of a slow page, so if it noticeably delays loading, consider a plain link instead.

Test it end to end before you rely on it
Run through the whole flow yourself as a customer would — submit a real entry — and confirm what should happen actually happens. Broken embeds fail silently, and the first person to notice is usually a customer who has already given up.
Tips & best practices
- ▸Brevo prices by emails sent rather than contacts stored, which is cheaper for large lists mailed occasionally and worse for small lists mailed often.
- ▸Sender authentication needs configuring properly or deliverability suffers. Do this before your first campaign.
- ▸The form builder is functional rather than elegant; expect to restyle the output.
- ▸Re-test the embed after any change to your site, your plan, or the connected account — third-party widgets break quietly and nothing tells you.
Common questions
How is Brevo priced compared to Mailchimp?
+−
Brevo charges by emails sent rather than by contacts stored, while Mailchimp charges by contacts. If you have a large list you email occasionally, Brevo is usually much cheaper. If you have a small list you email frequently, the difference narrows or reverses.
How do I add a Brevo signup form to my website?
+−
In Brevo, go to Contacts then Forms, build your form, and copy the embed code from the share step. Paste it into a code block on your site. Set up sender authentication for your domain before sending anything, or your emails will land in spam.
Do I need a developer to add Brevo to my site?
+−
No. Every option here is copy and paste into a code or embed block, which every mainstream website builder provides. The only genuine blocker is a builder or plan that does not allow custom code at all — Squarespace, for instance, requires a Business plan or above for code blocks.
Will adding Brevo slow down my website?
+−
Any third-party embed has some cost, because it loads code from another company's servers. One is usually unnoticeable; four or five on the same page is where small business sites become visibly slow. If page speed matters to you, prefer a plain link over a script wherever the option exists, and keep embeds to the pages that genuinely need them.
